Hello, My mom got operated in jan 2017, it was all good till Sept 2017 post that all of a sudden my mom's eye got red and started swelling.. We visited the doctor, he suggested few drops like megabrom. Whenever my mom uses the drops the eye gets back to normal, but then again after few days it gets red this is happening till now even after a year. All of a sudden my mom feels pain in her eyes post which the eye gets red and swells Need expert advice on what can be the reason and what can be done to cure it. Thanks, Nadir Ramani
